Robust spectroscopic optical probe

A USEFUL SPECTROSCOPIC SURVEYING DEVICE IS DISCLOSED FOR PERFORMING RAMAN, NEAR INFRARED, LUMINISCENCE, ULTRAVIOLET OR VISIBLE SPECTROSCOPES THAT IS FORMED WITH A SOLID METHOD OF CONSTRUCTION USING A METAL WELDING TECHNIQUE. THE REVEALED METHOD AND APPARATUS ESTABLISHES AN OPTICAL PROBE THAT IS EASY TO MANUFACTURE BUT ABLE TO SUPPORT DRASTIC ENVIRONMENTAL CONDITIONS WITHOUT SUFFERING DAMAGE AND PRODUCING USEFUL SPECTROSCOPIC RESULTS IN SUCH CONDITIONS. IN A PREFERRED MATERIALIZATION OF THE PRESENT INVENTION, THE OPTICAL PROBE (100) INCLUDES A CASE (101), CLOSED AT ONE END BY A TIP (102). TWO OPTICAL FIBERS (103 AND 104), ONE THAT SERVES AS AN EXCITATION CHANNEL FOR RADIATION FROM A SOURCE TO A COMPOSITION TO BE ANALYZED, AND ANOTHER THAT INCLUDES A COLLECTION CHANNEL TO TRANSMIT RADIATION FROM THE IRRADIATED COMPOSITION TO THE DETECTION MEANS , EXTEND FROM THE TERMINAL SURFACE (105) OF THE TIP THROUGH THE LENGTH OF THE HOUSING. A CAVITY (106) IS FORMED AT THE TERMINAL SURFACE (105) OF THE TIP (102), WHICH IS FILLED WITH CAST METALLIC WELDING, WHICH SOLIDS BY COOLING OVER A WELDER. THIS WELDER INCLUDES MEANS TO SECURE AND SEAL THE END OF THE FIBER OPTIC ON THE TERMINAL SURFACE OF THE PROBE TIP.
